A combat resolver for the classic Battletech boardgame

TODO: Write something actually useful here.

• Pull this repository into a Linux/Unix server with docker support installed
• Run build_producenugets.sh in repository root. This will create the Nuget files required by the client implementation and put them in the CustomNugets subdirectory where the build system needs them to be.
  • If you do not have a build system installed in the server and have a Windows system, run build_producenugets.bat therein and copy the files to the aforementioned place.
  • If you do not have a build system installed at all, and do not have access to my nuget feed, download the nugets manually instead. You can do this from the sidebar in the Github repository page. Save them to the CustomNugets folder in repository root.
• Go to the BtDamageResolverInfrastructure folder found in repository root
• Copy or rename the .env_sample file to just .env
• Type a secure password into the password environment variable in the .env file.
• Run refresh.sh

This will create a compliation docker image, create all BtDamageResolver project docker images, create a postgresql image, redis image and a grafana image, and start all of them. Everything should work automatically, but might take some time. Once all the images are running and the server program can be reached, a data import task will launch and populate the entity databases with initial data.

After the import data succeeds (should take a few seconds) the web client should be available and fully operational on port 8787 of localhost.

Unexpected characters in the .env file

This can be caused by Docker Desktop. Disabling "Docker Compose V2" from the settings of Docker Desktop might fix this.

Build can't find the NuGet files

If you downloaded the NuGet packages from GitHub manually, be sure that you renamed them correctly. The name should also contain the version number.

Unhandled exception rendering component: Cannot assign requested address (localhost:8080)

In some setups, Docker does not allow accessing localhost addresses. You can replace "localhost" with "host.docker.internal".

The following services are now available and running in containers:

• BtDamageResolver, which is not exposed to the outside world
• BtDamageResolverClient on port 8787
• PostgreSQL on port 65432
• Grafana on port 63000
• Redis on port 63790

Only the BtDamageResolverClient needs to be accessed by players, and it does not need a password. To access the rest of these services, use the password and username you set in the .env file. For users who do not need to access these services from the outside world, I would recommend firewalling all of them except the aforementioned BtDamageResolverClient.

To edit the external ports or adjust any service settings, edit the docker-compose.yml file in the BtDamageResolverInfrastructure folder.

To shut down the system, do the following:

• Go to the BtDamageResolverInfrastructure folder in repository root
• Type docker-compose down

This should bring down everything. The volumes are persisted, should you want to bring up the system later.

To start the system at any later time, do the following:

• Go to the BtDamageResolverInfrastructure folder in repository root
• Type docker-compose up -d

Normal docker prune methods should work once the system has been shut down. If you are sure that there is nothing in your docker installation that you want to keep, you can also do the following:

• Go to the BtDamageResolverInfrastructure folder in repository root
• Run prune.sh

Do note that the above will delete absolutely all dangling content in your docker environment. All dangling images, networks, volumes etc. Only use it if you have nothing in your docker you want to spare. It is included only because I want this to be usable by someone who doesn't know shit about docker and has only installed it to run BtDamageResolver.

The easiest way is to develop a client would be to use the nuget feed provided by Github to build the project and not worry about anything else. To accomplish this, one can add the following source to your Nuget.config:

<add key="githubWarma" value="https://nuget.pkg.github.com/Warmag2/index.json" />

To be able to use the source, add the following credential block in its entirety or add the githubWarma source to your credentials block:

<packageSourceCredentials>
  <githubWarma>
    <add key="Username" value="Warmag2" />
    <add key="ClearTextPassword" value="INSERT_READ_ONLY_NUGET_FEED_PAT_HERE" />
  </githubWarma>
</packageSourceCredentials>

Unfortunately Github watches the commits I push into this repository, and if they contain the hash for the PAT, the PAT will be immediately revoked. Therefore I cannot share it in this readme directly. I guess this service isn't meant for actually allowing others to access your feeds or repositories or something.

To circumvent this, mail me or contact me in IRC (Ircnet/Warma), and I will give you the read-only PAT so you can read the feed and get those nugets.

I will fix this later if someone tells me how to do it properly.
